Question 1

How do I spot a fake or shady locksmith before I get burned?

Accepted Answer

A few things to watch for specifically when calling about a Chrysler remote head key job.

If someone quotes you a vague "starting at" price on the phone and then adds cutting fees, programming fees, and emergency fees once they are standing in your driveway, that is a bait and switch. It happens more than you would think. One owner agreed to a low base price and got handed a bill more than double that before the tech would hand the key over.

Look them up before they arrive. No real address, no reviews that mention specific vehicles or situations, a stock photo for a profile image, those are all signs. A legitimate automotive locksmith who works on Chryslers can tell you what equipment they use, whether the job involves OBD programming, and roughly how long it takes. If they go vague on any of that, keep looking.

Also, do not let anyone start work without agreeing on a total price first. In writing, even just a text.

Question 2

What exactly is a remote head key and why can't I just get one copied at a hardware store?

Accepted Answer

A remote head key is a single unit that does two jobs. The metal blade cuts into the ignition and operates the locks mechanically. Built into the plastic head is a transponder chip that the immobilizer reads every time you turn the key, and a small RF transmitter that runs the lock, unlock, and trunk buttons.

A hardware store can copy the blade. That is it. The blade copy will open your door and turn your ignition, but the car will crank and immediately stall because the immobilizer does not recognize the chip. You need professional equipment to program the transponder side so the car actually runs.

The 2006 Chrysler 300 is old enough that this does not involve the newer secure-gateway access requirements that show up on more recent vehicles. But it still needs the right tools and the right procedure. It is not a job for a generic key machine at a big box store.

Question 3

What equipment do you actually use to program a 2006 Chrysler 300 key?

Accepted Answer

For a 2006 Chrysler 300, the programming goes through the OBD port. I use professional automotive key programming platforms that can read the immobilizer data, extract what the system needs, and write a new key into memory. On a vehicle this age, there is no secure-gateway access requirement, so the process is more direct than on newer models.

That said, having more than one tool platform matters. Chrysler immobilizer jobs from this era can sometimes hit a wall with one tool and respond cleanly to another. I carry multiple platforms for exactly that reason.

For all-keys-lost, the process takes longer because the system has to be accessed from scratch rather than adding to an existing key list. If you have one working key, adding a spare is faster.

Question 4

My 2006 Chrysler 300 starts fine but the remote buttons stopped working. Do I need a whole new key?

Accepted Answer

Not necessarily. This is actually one of the more common calls I get on these.

First, swap the CR2032 battery. The remote side of the key is more sensitive to a weak battery than the transponder side, so the car keeps starting while the lock and unlock buttons go dead. A fresh battery with clean contacts fixes it more often than you would think.

If the battery does not help, the fob may have lost its pairing to the vehicle's receiver. That can sometimes happen after a battery swap if the key was left in a low-power state too long. Re-syncing the remote does not always require full OBD programming, depending on what exactly dropped out.

If the shell is cracked or the buttons feel mushy and unresponsive, the internals may have failed. That is when a new remote head key, properly programmed, is the right call. But start with the battery.

Question 5

Can I program a second key myself if I already have one working key for my 2006 Chrysler 300?

Accepted Answer

There is an onboard add-a-key procedure for this generation that works when you already have a functional programmed key in hand. It involves a specific sequence using the existing key and the ignition, and it can enroll an additional remote head key without any external tools.

The catch is that the procedure is timing-sensitive and has to be done in the right order. If you own a second uncut, unprogrammed key and want to try it yourself, the information is out there. Some owners pull it off fine. Others get the sequence slightly wrong and have to start over, or end up locking themselves out of the programming mode.

All-keys-lost is a different situation entirely. No working key means no onboard procedure. That requires professional equipment to access the immobilizer directly. Do not let anyone tell you otherwise.
